Starkbierfest. Aventinusfest. Madnessfest! Madness? Almost suicidally so, I'd say, a fest where the main beverage is a glass of beer with almost 7! units of alcohol.
As mentioned, before the two days in Obertrum I begun my trip a week earlier in München, beer capital of the world for sure! Famous for Oktoberfest, but a city that offers so much more.
